SIGNAL

monetized signals — pay per notification
Anti-spam • Verified • Micropayments

Pay to deliver. Get paid to accept. A real market for webhooks.

Signal is a lightweight payments layer for outbound signals: developers pay to send verified webhooks and receivers earn for accepting them — turning noisy, unactionable pings into valuable, monetized signals.

Verified Delivery

Crypto-backed signatures + routing guarantees ensure only authorised senders make requests.

Anti-spam Economics

Senders stake a small fee; receivers choose whether to accept. Spam becomes expensive.

Composability

Easily layer Signal into existing infra: message queues, event routers, alerting systems.

How it works

Simple primitives. Clear incentives.
1

Sender stakes a payment

When a sender posts a webhook, a small payment is staked to the message. That payment covers delivery & optional processing fees.

2

Receivers decide

The receiver (service or human) can accept, reject, or require more info. Accepting releases the payment to the receiver; rejecting refunds or burns per policy.

3

Verified delivery

Signal records an immutable proof of delivery and signature — useful for billing, audit, or SLA claims.

Developer quickstart

Two lines to send a verified, paid webhook.

// Node.js (example)
import fetch from 'node-fetch'

const res = await fetch('https://api.signal.sh/v1/send', {
  method: 'POST',
  headers: { 'Authorization': 'Bearer sk_live_xxx', 'Content-Type': 'application/json' },
  body: JSON.stringify({ to: '/hooks/alerts', payload: { event: 'deploy' }, value: 0.005 })
})
const json = await res.json()
console.log(json)

Responses include a delivery token you can use to track status, verify proofs, and request refunds.

Security & anti-spam

  • Signed payloads — HMAC & optional blockchain-backed receipts.
  • Sender reputation & staking reduces unsolicited traffic.
  • Rate limits, whitelists, and machine-learned heuristics for automatic rejections.
